the area of trapezium is 360m² , the distance between two parallel sides is 20 m and one of parallel side is 25m. find the other parallel side
Answers
Step-by-step explanation:
let the other parallel side be x
area of trapezium is = 1/2 × sum of parallel sides × height
360 = 1/2×25+x×20
360×20=25+x
36=25+x
36-25=x
11=x
hence the other parallel side is 11
hope this is helpful for you ❤️❤️
Area of a trapezium =360m²
Distance between two parallel sides =20m
one of parallel side=25m
Area of a trapezium=½×distance between two parallel sides ×sum of parallel sides
Let the other parallel side be 'x'
According to the question=>½×20×(25+x)=360m²
=>10×(25+x)=360m²
=>(25+x)=360÷10
=>(25+x)=36
=>x=36-25
=>x=11m
Therefore, the other parallel side is 11m.
hope it will help you.
